For BCI to progress as a viable compliment to
traditional video games control and be accepted and
adopted for commercial use, there are a number of
impediments to overcome. One of the main technical
issues restraining commercial use of BCI is latency.
BCI latency refers to the time it takes for a BCI
system to read, classify and convert the raw
electroencephalography (EEG) signals into a useful
command for a computer system to use. Existing BCI
hardware also impedes widespread adoption of BCI
technology due largely to cumbersome, expensive
equipment and long setup times. However in recent
years companies such as Emotiv [8] and NeuroSky
[9] have developed wireless, dry electrode headsets
which negate the requirement for wired interfaces to
EEG equipment and conductive gel to be used during
hardware setup. Advances such as these, along with
consumer grade pricing ensure that BCI hardware
will be an attractive technology in the future.
Advances in EEG technology such as this helps to
endorse BCI use in commercial video gaming by
promoting ease of use and low prices. In recent years,
advances in signal processing methods for BCI [10]
have aided researchers in detecting relevant
information more accurately from the nOIse

contaminated and non-stationary neural signals
produced by the human brain.
